2. Open the cookie bags and set down a layer of Oreos, then Chips Ahoy and so on until you have a layer of all the cookies filling up the baking dish. Use which ever order you want or mix up the different types of cookies within the layers.

3. Cover the finished casserole with foil over the top of the dish.

When it comes time to bring your contribution to the party, put on the oven mitts and march in holding the dish carefully. Peel back the foil and let the hunger games begin. (May the Oreos be ever in your favor!)

Additional suggestions: For healthier options, use Snackwells or other reduced-fat cookies. Before the party, check to see if anyone has for nut allergies.
